Content:
This class contains all the morphological operators, as dilation, erosion, or watershed, for the 4 conexity. Of course,as the structring elements are 4-conected, results such as watershed or skeleton are 8-conected.

Warning:
This paragraphe has to be enhanced !!!


Member Function Documentation

CImageGrey * CMorpho4c::geodesicErosion ( CImageGrey * mark,
CImageGrey * ref,
int border ) [virtual]
 

Geodesic Erosion.

This function compute the geodesical erosion of the image mark above image ref. In other words, it computes iteratively until stability the erosion of mark by an hexagonal ball of size 1, and takes the union of the result with ref.

Reimplemented from CMorpho.
